asp衔接Mssql的办法及常见的差错 //第一种写法: MM_conn_STRING = "Driver={SQL Server};server=(local);uid=sa;pwd=;database=infs;" Set conn = Server.Createobject("ADODB.Connection") conn.open MM_conn_STRING SET RS=SERVER.CreateObject("ADOBD.recordset") SQL="SELECT * FROM TABLE ORDER BY ID DESC" RS.open SQL,CONN,3,3 //第二种写法:(DSN衔接) MM_conn_STRING="DSN=BBS;UID=SA;PWD=12345" Set conn = Server.Createobject("ADODB.Connection") conn.open MM_conn_STRING SET RS=SERVER.CreateObject("ADOBD.recordset") SQL="SELECT * FROM TABLE ORDER BY ID DESC" RS.open SQL,CONN,3,3 // 3,3是改动、删除、增添开关! //第三种写法: MM_conn_STRING_own = "Driver={SQL Server};server=(local);uid=sa;pwd=11111;database=infs;" Set conn = Server.Createobject("ADODB.Connection") conn.open MM_conn_STRING_own //第四种 - 这种方式用在ACCESS中 strconn = "DRIVER=Microsoft Access Driver (*.mdb);DBQ=" _ & Server.MapPath("asp.mdb") set conn = server.createobject("adodb.connection") conn.open strconn 实现方式一: <% dim conn set conn=server.createobject("ADODB.connection") conn.open "PROVIDER=SQLOLEDB;DATA SOURCE=(local);UID=用户名;PWD=密码;DATABASE=数据库" Set conn = Server.CreateObject("ADODB.Connection") DSNtemp="DRIVER={SQL Server};SERVER=(local);UID=用户名;PWD=密码;DATABASE=数据库" conn.open DSNtemp %> 实现方式二: <% option explicit dim startime dim conn dim connstr dim db,pass_word,User_ID,Data_Source startime=timer() db="数据库名称" Pass_word="帐号密码" User_ID="登陆帐号" Data_Source="服务名称或者ip" Set conn = Server.CreateObject("ADODB.Connection") connStr="Provider=SQLOLEDB.1;Password='"&pass_word&"';Persist Security Info=True;User ID='"&User_ID&"';Initial Catalog='"&db&"';Data Source='"&Data_Source&"'" conn.Open connstr function CloseDb Conn.close Set conn = Nothing End Function 常见故障 (a) Microsoft OLE DB Provider for ODBC Drivers 过错 '80040e57' [Microsoft][ODBC SQL Server Driver][SQL Server]String or binary data would be truncated. 这是由于数据库表中字段的字节数太小了。 (b) 出错提醒: Microsoft OLE DB Provider for ODBC Drivers 过错 '80040e57' [Microsoft][ODBC SQL Server Driver][SQL Server]Arithmetic overflow error for data type smallint, value = 32768. 是由于字段的类型是smallint太小了应改成int. (c) icrosoft OLE DB Provider for ODBC Drivers 过错 '80040e4d' [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'user78'. /index333.asp,行30 数据库的用户名或密码不对. (d) Microsoft OLE DB Provider for ODBC Drivers 差错 '80004005' [Microsoft][ODBC 驱动程序 管理器] 未发明数据源名称并且未指定默认驱动程序 /include/conn.asp,行3 这种现象的原由是:1.web服务器没有准确设置数据源, 须要您提供主机名和数据库IP地址,发信件到LIVEPERSON ,为您在服务器上树立数据源,方能正常调用。 本文来自CSDN博客,转载请标明出处:http://blog.csdn.net/fredrickhu/archive/2009/09/20/4573228.aspx
